This work develops an innovative perimeter loop configuration aimed at surpassing the limitations of conventional alarm systems. The proposed design enables the integration of a large number of sensors into a single monitoring loop, using only two connecting wires, and is compatible with the commonly used normally closed (NC) connection. The custom perimeter system features simplified installation with the use of standardized parametrizing resistors, and includes a calibration method to enhance detection accuracy. A prototype was tested with 20 magnetic contacts, demonstrating that wire resistance and the tolerance of parametrizing resistors are critical factors influencing system performance. In practical trials, a maximum of 15 sensors could be reliably detected. However, the introduction of calibration procedure allowed for an increased detection of up to 20 sensors. The system, which can handle numerous closely spaced control points, also features battery backup capability to ensure operation during power failures. Overall, the system effectively manages complex monitoring requirements and provides reliable performance under various conditions.
